After our contest blowout last week, we wanted to sneak in one more before the weekend so we don't seem like slouches. You may remember we checked out Twitterlerts earlier this month. The app is a twist on the standard Twitter client, and lets you search for topics or keywords and set alerts on your device. Its a handy app to have to keep tabs on your brand, favorite topics and more.You can set multiple alerts, and never miss a thing on Twitter. Twitterlerts is on sale now in the CrackBerry App Store for $4.99.

We have 50 free copies of Twitterlerts to give away. Just leave a comment on this post to be entered. Contest ends this Sunday at Midnight PST. Please only leave one comment, multiple submissions won't count.
